Although this prominent limestone wall crowns the Boomerang Park, it has never been climbed straight up. Ken (the developer of the park) has red pointed it twice, but each time has had to work over to the right near the summit. As with other straight sided limestone hills in this area (Thais call them mountains or 'pu kao', because they're the tallest protrusions for hundreds of miles) - they're generally smoother at the lower ends, and sharper at their upper reaches. There is a steep 'n rocky gully up its left / western side, so it's a non-technical way to ascend to the summit. The top has a 200 degree sweeping view of Chiang Rai town as well as large portion of the river valley, including other hills - stretching out for twenty five miles or more.

About 200 meters SW of Boomerang Park is a long hill which parallels the Mae Kok river (which flows out of Burma in the west, to merge with the Mekong river in the east). Called 'Crouching Lion Hill' it has a Buddha Cave on its west end, and a through-the-hill 3-chambered cave near its west end. This photo shows some undeveloped and never-been-climbed rock walls at its east end. The white marblelized rock face would be particularly challenging - for some daring climber.

view of upper part. Located 2 Km nw of Chiang Rai, northernmost Thailand. This wall has been climbed twice solo without aid, though each time KenA wound up veering to right at upper 20% because of steepness and danger factor. It can be summited by bouldering up its west (left) side.

Spikul, two existing routes to the summit. Both need rebolting. Currently establishing two new routes. My wife and I are putting up the highest point on the right via face and crack climbing. Shuld be 18 pitches when complete.
